摘要
生态足迹是一种衡量人地协调和生态可持续性评估的方法。运用生态足迹模型,采用可变世界单产法从区域角度计算了长江三角洲地区1996—2004年间生态足迹和生态承载力。研究表明,随着人口的不断增长与经济的持续发展所带来的消费水平的不断提高,该区域生态赤字在不断增大,人地关系处于不协调发展状态,威胁着区域生态系统的稳定性和可持续发展。
Ecological footprint is an important indicator to evaluate the sustainable use of ecosystem. Based on the theory of ecological footprint, the ecological footprint and ecological capacity of the Yangtze River Delta during the period from 1996 to 2004 are calculated and analyzed using the method of variable world average yield. Results show that the ecological deficits continue to increase, which demonstrates that great humanenvironment conflicts exist. The Yangtze River Delta is in a state of unsustainable development.
